controlled livestock or poultry facility. Using this equipment for any other purpose or in a way not within the
operating recommendations specified in this manual will void the warranty and may cause personal injury. This
manual is designed to provide comprehensive planning, installation, safety, operation, and parts listing
information. The Table of Contents provides a convenient overview of the information in this manual. The Table
of Contents also specifies which pages contain information for the sales personnel, installer, and consumer (end
user).
Safety Information
Caution, Warning and Danger Decals have been placed on the equipment to warn
of potentially dangerous situations. Care should be taken to keep this information
intact and easy to read at all times. Replace missing or damaged safety decals
immediately.
Using the equipment for purposes other than specified in this manual may cause

Keep safety signs in good condition. Replace missing or damaged safety signs.
Decal Descriptions
DANGER : Electrical Hazard
Disconnect electrical power before inspecting or servicing equipment unless
maintenance instructions specifically state otherwise.
Ground all electrical equipment for safety.

Introduction to Control
Expanded Backup Control Introduction to Control
MT1805A

The Chore-Tronics®
Expanded Back-up Control
contains relays that are pre-wired
for use with Backup Thermostats (Not Supplied). These relays are sized to conduct
the actual motor current in one line of the power to the Fans being backed up. Each
Relay can have a maximum of two independent 1hp loads wired to it.
Each Output Relay is wired to a Toggle Switch (Item 1, Figure 1). The Toggle
Switch allows the user to determine whether or not a fan or fans should turn on when
the back up thermostat that the fan is connected to turns on. There is also a toggle
switch that allows the user to determine if the Tunnel Curtain or the Sidewall Air Inlet
Doors open when Thermostat 1 turns on (Item 2, Figure 1).

Never place all of the Toggle Switches associated with any one Thermostat in the
"Not Active" position. This will result in no Fans or Heat Zones turning on when the
Backup Thermostat turns on.

The Expanded Backup Control can have a maximum of 5 Backup Thermostats
connected to it.

Thermostat Temperature Settings
As with all backup systems that depend on mechanical Thermostats, it is essential
that the temperature settings of the Thermostats be adjusted close enough to the set
temperature to protect the livestock or poultry. Every time the set temperature of the
electronic control is changed, the Backup Thermostats must be adjusted
appropriately.
Danger !
Do not cross phase. The other leg of the power to the motors goes directly to the
motors.
The 24 VDC Input of this Back-up Box is meant to be connected to the 24 VDC
output of the control being backed up.
